A novel method for deploying a stent into a highly angulated position through use of a stent strut: application of a five-in-seven system.

Provisional stenting of the side branch seems to be an attractive strategy even in the DES era. One of the technical problems in provisional side branch stenting is how to deliver the stent through a stent strut. In this case presentation, we suggest a novel method for deploying a stent through the use of a 5 Fr guiding catheter. A 5 Fr guiding catheter within a 7 Fr guiding catheter was advanced to the lesion, through a stent strut, facilitating the deployment of the stent. This system permits negotiation of the stent strut that otherwise obstructs stent passage.
